1. We can't draw graphs for you here. You will have to get some graph paper and draw your own. It will be good practice for you.

The first equation has a local maximum or minimum at x = + or - sqrt(5/6)
The second funtion has a local maximum or minimum at x = + or - sqrt(2/3)

When you draw the curves you will see which are maxima or minima. Both have one of each.

3. ### how to sketch a graph of..

Local minimum and local maximum imply that the function approaches negative and positive infinite at opposite sides of the graph. Local minimum (1,1) and local maximum (3,3) means the slope of the function is 0 at these points.

9. ### Minima Maxima

Find and classify the relative maxima and minima of f(x) if f(x)= defint a=0 b=x function= t^2-4/(1+cos(t)^2) dt x^2-4/(1+cos(x)^2)= 0 x^2-4=0 x^2=4 x= +/- 2 So I got relative maximum as -2 and 2. And relative minimum as zero.
